Impulse buy on clearance from a well know online store. Using it primarily as a suppressor host. Anyone have one? If so what brands of ammo does it like, did you mod the trigger with an aftermarket 10/22 model to improve the pull? What kind of a scope did you put on it? Basically, looking for input on making it as accurate as realistic without spending more on aftermarket parts than the gun cost. For those who don't know anything about it (and I was one of them) it is a straight pull action, polymer stock with adjustable pull and a detachable barrel. It uses 10/22 magazine and converts between 22lr and 22wrm just by a tool-less barrel change. Attached File Attached File |

Hickok 45 had a review on Youtube and was the first I’d seen since it hit the market. From Hickok 45 review the tested rifle seemed to function reliably and was decently accurate. I can see where the straight pull action might be quicker than a traditional bolt action. I think it was a good choice to use the Ruger 10/22 pattern magazine. Hammerli is a sister Company to Walther and there are 1911 22 LR pistols that get decent reviews. |

It was $355 shipped without tax so I am not expecting it to be a 1 MOA gun. One review I read put it on-par with an out of the box standard barrel 10/22 in terms of accuracy. The trigger is supposed to be the weakest aspect but it supposed to be a clone of the Ruger system so that a drop-in trigger group will fit. What I don't know is if individual components are identical. I can't see putting a two or three hundred dollar trigger pack in a gun that only cost $350. I will have to do some research on that. I doubt that I will ever bother to pick up the 22 magnum barrel. I have a CZ455 with a 22lr and 17 hrm barrels and haven't ever put the 17 on it. I do like the being able to break the Hammerli down some for transport although it only reduces the length by about 6 inches or so which isn't as nice as the 10/22 breakdown. I originally just wanted to get a threaded barrel for the CZ but factory ones are like hen's teeth and when this deal came up I decided it was worth a chance to get an inexpensive and kind of unique suppressor host. From the videos I have watched it is super quiet with a can. |

I have one and like it however it's not without some faults. The action does come well "greased" and the straight pull operation is pretty cool. The trigger / sear parts are different since this is a bolt action not a semi auto firearm. Here are some of my thoughts I posted on another board that I frequent; I bought the plastic stock 22LR version at my local PSA store - $349.99. In reality that might not have been as much of a sale as PSA would have you believe since the retail MAP is shown at $382.00 It's an interesting design from the QD barrel to the 6 position buttstock and you can flip the rubber check piece for a higher check weld. It has a M-Lok rail on the underside of the handguard too. Came with one mag plus two plastic adapters that fit on 10/22 22LR mags so they will fit in the longer 22 Magnum length B1 magwell. Out of the box the trigger feels heavy and with that QD barrel I don't expect one hole groups. On the other hand it should be a fun suppressor host and possibly a good varmint getter. I'm not interested in a 22 Magnum barrel but the 17 HMR option sounds appealing if it becomes available. I threw a very old Leupold 2-7 VX3 scope on it, this was a poor choice for shooting inside 50 yards and the trigger needs work. By pure luck it did group a couple types of ammo into a nice tight clover leaf cluster that you could cover with a dime but most stuff was just meh at this point. I have little doubt that with a decent optic and some trigger work it will deliver better groups with most ammo. You need to work the toggle with some vigor or the empty case won't be ejected, otherwise the action cycled nice & smooth without any feeding or extraction issues. Oh and the ambi mag release is sweet - its easier to remove or drop a mag than either of my 10/22's. My buddy shot maybe 10 or 12 rounds and was able to do better than I was. Most of the ammo we shot were subs with a "Q" El Camino mounted. No idea how it will group without a can. I'm probably going to spend more on a scope than I paid for the rifle! Thought I'd add something to this thread about the trigger group. You'll see claims that the Ruger 10/22 trigger group and its parts are compatible, well thats only half true. I have not tried it but it appears that you could take a complete 10/22 trigger group and mount it the rifle and be G2G. However I don't believe you're going to be able to swap out individual pieces with Ruger parts - here are a few reasons why. 1 - the trigger housing is a two piece plastic unit with a fixed ejector and its much smaller than the Ruger part. 2 - the trigger & sear pieces are slightly different because the Hammerli trigger has a integral blade like safety feature. 3 - the hammer strut is pinned to the hammer. 4 - the hammer spring is not captured on the strut instead Hammerli uses a collar that serves as a spring perch which fits in a pocket molded into the housing. 5 - disassembly & reassembly of the Hammerli housing is FUN and I launched the hammer spring collar to some unknown region of my garage! Hammerli CS is pretty good and they sent me a new collar, took a couple weeks as they didn't have any on hand. I'm sure I'll find the original collar 2 years from now. Bottom line is that I think swapping the Hammerli pack out for a Ruger is the way to go since trying to disassemble, polish parts, then reassemble multiple times is a PITA. |

Thanks, that is very useful information, especially the part about the individual trigger components not being very likely to be compatible with ones for a 10/22. I will probably shoot a few hundred rounds through it and, if I like it enough, pony up for a new trigger pack. |

I ordered one, took it out for a spin yesterday. The stock is ok but feels cheap. The bolt toggle originally was absurdly difficult to unlock, but after a few hundred toggles it's somewhat easier to unlock, but still requires two fingers to unlock and a push with the palm heel to lock. I put a cheap 6x from Primary Arms on it, a MagPul bipod and shot it out to 25 yards at an indoor range using Mini-mags and some Aguila Super Extra. The trigger is not great, once I got a zero on the scope it was making maybe an inch pattern with called fliers. The scope has an ACSS reticle with 22 BDC and the dot at the center was tough to find in the indoor range with meh lighting. The mini-mags cycled fine, only had one misfeed due to not pushing the toggle forward vigorously enough. The Super Extra with its short brass tended to not fully eject and get stuck in the action, requiring me to drop the magazine to clear the malfunction. I've got roughly 150 rounds thru it at this point and I like it better than a 10/22. The stock is ok, the adjustable LOP is nice but the butt is weirdly angular and uncomfortable. I've got a Ruger BX1 trigger group on the way and I'm going to swap out the fixed 6x for a fixed 10 I have laying around. I'll report back on the BX1 upgrade. |

Mine showed up last week but I hadn't posted a follow up. I will echo some of your thoughts. The bolt was super stiff out of the box but I sat for about 10 min working it and mine must be much be smoother than yours. I can close it with just my trigger finger and don't need to palm it shut. I suspect yours will work its way up to that point with some additional exercise. I agree, the trigger is pretty meh and the leaf is really narrow and uncomfortable. Let me know how the BX1 works if you don't mind since that seems to be the best budget upgrade on a pack. I find the stock to be pretty comfortable and don't have a big issue with the hand positioning. The stock is really light which I guess could be considered to be the same as cheap feeling but nothing that bothers me very much. I tried it with the riser up and down and for me at least I like it down better but that could change if I put different glass on it. Right now I just have a Bushnell airgun scope on it off of my springer that I hadn't shot lately. I need to get a dedicated scope but haven't decided on one yet. So far I have only run about two magazines of CCI standard velocity through it with my suppressor attached. Function has been fine. Need to get it on the bench to see what it likes best though. The barrel lockup on the air hose fitting is really tight on mine. I haven't tried removing the barrel and checking for retention of zero but that has to happen if I intend to disassemble it for transport. |

BX1 trigger installed, it's much nicer than the stock Hammerli trigger. Better than a factory 10/22 and a little gritty compared to a Volquartsen parts build I have. It has a clean break and I am looking forward to trying it out. The pins holding the trigger group practically fell out, so be careful of that when removing the action from the stock. The action screws are two lengths, short to the front and long to the rear behind the trigger guard. I didn't notice they were different length until after the long screw bottomed out in the front hole. The BX1 seems to be a good fit. I was a little worried that I'd need to inlet the stock a little to accommodate the different shape of the BX1 but it ended up fitting just fine. Remember to center the safety stud up as best you can when you are fitting the action back into the stock. Magazines fit and remove without difficulty. The BX1 magazine release isn't as nice as the Hammerli module, but the better trigger more than makes up for it. Didn't put a rounds through it yet but I am optimistic that it will function. |

Thanks for the confirmation on the BX1 group fitting and the installation tips. In the spirit of the cheap plinking 22 this was supposed to be, the BSA Sweet 22 scope I ordered just arrived yesterday. I am going to shoot a few boxes through it this weekend with the stock trigger and then very likely order the BX1 pack. All in with the trigger pack it still won't be as expensive as the suppressor I bought it to pair with |
| I am very glad you posted this. My local gun store has two of them for a very good price, but I have a fantastic CZ bolt .22. I think I am just looking for a reason to buy a new gun. I have the disease. The Straighr pull action is intriguing, but I'm not going to do it. |

Well I took the Hammerli out for an extended outing today but the jury is still out. The barrel seems pretty sensitive to getting the proper lockup after being removed and reattached. After I put it back on I had a number of light primer strikes and failures to ignite primers. At first I thought it was the really old ammo I was using since I was testing out a bunch of partial boxes of various match ammo. Then I began to speculate the firing pin was damaged or there was some other problem with the bolt since it wasn't extracting consistently. Then the fun part happened where I had a partially out of battery ignition that blew crap (unburned powder and gas) back in my face and left a partially mushroomed case in the chamber. There was some talk that this rifle will fire out of battery and that confirms it. Not really a great design. At that point I was ready to box the thing up and send it back to them but I though to myself, if the barrel isn't fully seated it would be too far forward and could cause the light strikes and failures of the extractor to engage. I pulled and replaced the barrel, being very careful to make sure the air fitting was fully snapped closed (I thought I had before mind you). After that everything worked as designed, although I expect it will still fire out of battery. I didn't particularly hate the trigger. It is heavy but mine only has a little creep. I don't have any 10/22s with nice triggers so perhaps it is just an issue of you don't know what you are missing if you never had it. It is really, really, quiet with my AAC Halcyon suppressor on it running subsonic ammunition. Much more quiet than my springer air rifle. Groups are decent but I was mostly testing function and getting the scope close so my target was only set at 25 yards and I need to get something out further to say much more. Today I am going to do a bit more testing by removing and replacing the barrel again. If it doesn't have any hiccups I will assume I am the problem. |

I’m considering getting one of these. PSA has a switch barrel .22 LR/.22 Mag one of these on sale for $549. Seems like a good deal. If I knew for sure I could get a barrel in .17HMR to go with the rifle I’d definitely be sold. https://palmettostatearmory.com/walther-force-b1-combo-22lr-22-wmr-bolt-action.html |

Every place I have looked says sold out. It does appear that a .17HRM conversion kit is produced but all the literature on them is in French from Umarex so I don't think they are being imported. |

OK, I bought one a couple months ago. My observations follow. Trigger broke very clean......... but..... at 6.5 lbs. The stupid extra blade dingus makes it hard to get a good finger placement on the trigger. I removed it from mine. That alone made it about 1/2 pound less. I polished everything and got it down to 4.5 lbs, but now have just a hair of noticable creep. (I also lost the hammer spring retainer, and had to get a new one. You can snake some .020 safety wire up in there and fashion a tether before pulling it all apart. I did this on reassembly. Customer service folks were great.) Swap barrel from 22LR to 22MAG or vice versa requires about 22MOA adjustment left to right, and 14 up down. Gotta yank that thing to eject the cases, 22LR especially. LR's that don't get ejected will end up behind the top of the mag, and that's a pain in the ass. Groups I thought were marginal, but on seeing a buddies Ruger Precision rimfire with Ely Match, I guess it's not that bad. Rugged Occulus causes shift in POI with the 22 mag, but not 22LR. Probably a barrel seating issue. Biggest gripe is extraction. It's weak. And looking at that extractor without removing it yet, I wouldn't be surprises if it's plastic. It looks odd, i"ll probably pull that out next and have a look. The thoughts above on proper barrel seating affecting extraction definitely have merit. So, knowing all this, I can't recommend one. Since I'm kinda all in now, I'll make it shoot enough to call it my 22mag rifle. Oh, I ran mine with my 10/22 lower in it too to prove it works. It does. But yes, you lose that amazing mag release, so i'll keep the oem and keep tuning it. |

If interested, PSA has dropped the price to $469 for the combo. https://palmettostatearmory.com/walther-force-b1-combo-22lr-22-wmr-bolt-action.html |

I think if you want the 22 WMR you pretty much have to buy the combo since I have never found anyone who had the barrel alone in stock. |

Thought I'd add a bit more to the thread. Bought a used Vortex Viper HS 4-16x50 scope a few weeks ago and went out to zero it yesterday. The range was busy and the wind was gusty so I wasn't able to do any accuracy testing so no updates on that front. I did experience a bunch of light strikes and I believe it may have been due to closing the bolt too softly. It seemed like once I closed the bolt with more "effort" all of these rounds fired on the second try. Not much to report other than that and I still think these rifles make a nice suppressor host. Here are some pictures of the hammer & strut and spring. You can see how they differ from the Ruger strut (beside it) especially the pinned hammer strut and its spring cup. A bit of the plastic FC module can be seen in the lower left of the pic, that pocket is where the hammer spring seat or cup rests. Love to know if anyone has tried trimming a coil or two off the hammer spring to yield a lighter trigger pull.

Bit of an update with this rifle. I installed a Ruger BX 10/22 drop-in trigger which is a huge improvement over the stock Hammerli piece. I had been reluctant to do this because I feared mag changes would become a PITA since the factory mag release is freaking awesome. Good news - mags still drop out easily and the trigger is outstanding. Bads news - light strikes are now a thing, sometimes as many as 3 rds in a 10 rd mag. Things improved throughout the day but not perfect, time will tell. It ain't no precision rimfire match gun but it is a fun suppressor host so I plan to keep dinking with it to see what it can do. |
